Solaris ZFS Wiki

Welcome to the ZFS page on java.net!

This is the main page where you can learn about ZFS if you haven't used it before or if you have used it for years and want to learn more about the latest features. We're just getting started so please stay tuned.

What is ZFS?

ZFS provides simple administration, transactional semantics, end-to-end data integrity, and immense scalability. ZFS is not an incremental improvement to existing technology; it is a fundamentally new approach to data management. We've blown away 20 years of obsolete assumptions, eliminated complexity at the source, and created a storage system that's actually a pleasure to use.

ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of file systems can draw from a common storage pool, each one consuming only as much space as it actually needs. The combined I/O bandwidth of all devices in the pool is available to all file systems at all times.

ZFS administration is both simple and powerful. Check out the documentation section.
